The four functions below supplement the four corresponding type constructor functions from MPI-1. The new functions are synonymous with the old functions in C/C++, or on Fortran systems where default INTEGERs are address sized. (The old names are not available in C++.) In Fortran, these functions accept arguments of type INTEGER(KIND=MPI_ADDRESS_KIND), wherever arguments of type MPI_Aint are used in C. On Fortran 77 systems that do not support the Fortran 90 KIND notation, and where addresses are 64 bits whereas default INTEGERs are 32 bits, these arguments will be of type INTEGER*8. The old functions will continue to be provided for backward compatibility. However, users are encouraged to switch to the new functions, in both Fortran and C.
The new functions are listed below. The use of the old functions is deprecated.

Advice to users.
Current Fortran MPI codes will run unmodified, and will port to any
system. However, they may fail if addresses larger than 232 -1
are used in the program. New codes should be written so that they use
the new functions. This provides compatibility
with C/C++ and avoids errors on 64 bit architectures. However, such
newly written codes may need to be (slightly) rewritten to port to old
Fortran 77 environments that do not support KIND
declarations.
( End of advice to users.)

You can draw disabled text, like that you see when you set a TLabel's Enabled property to false, by using the DrawState Windows API function.
The following routine draws disabled text on a canvas using the canvas' current font:
function DrawDisabledText(const Canvas: TCanvas; const X, Y: Integer; const Text: string): Boolean; begin Result := DrawState( Canvas.Handle, // device context to draw on 0, // brush (not required) nil, // output function (not required) Integer(PChar(Text)), // text to be rendered Length(Text), // length of text to be rendered X, Y, // co-ords of top left of text 0, 0, // size of text (not required) DST_TEXT or DSS_DISABLED // text type and state ); end;
The DST_TEXT flag tells the API routine to display text and DSS_DISABLED tells it to draw the text disabled.
If your text contains accelerator characters (i.e. uses the "&" sign to cause the following character to display underlined), then use the DST_PREFIXTEXT flag in place of DST_TEXT.
In this example we will display the text "Hello World!" in the default font both normally (using Canvas.TextOut) and disabled (using DrawDisabledText).
Start a new VCL application and create an OnPaint event handler for the form as follows:
procedure TForm1.FormPaint(Sender: TObject); const cText = 'Hello World!'; begin Canvas.TextOut(8, 8, cText); DrawDisabledText(Canvas, 8, 32, cText); end;
If you want to use a different font, set the canvas' font property as required before calling DrawDisabledText. For example to change the above code to use 14pt Arial Bold, revise the FormPaint method as follows:
procedure TForm1.FormPaint(Sender: TObject); const cText = 'Hello World!'; begin Canvas.Font.Name := 'Arial'; Canvas.Font.Size := 14; Canvas.Font.Style := [fsBold]; Canvas.TextOut(8, 8, cText); DrawDisabledText(Canvas, 8, 32, cText); end;

It was at my grandma's where my story started to unfold. I realized that I was alone. Too alone. Not another living soul, anywhere. Just some luggage discarded in the backyard. And stuff which did not have any right to be in the backyard. Greyish stuff. Not entirely opaque. Better not looking up, I knew that the source of the light here was not a bright autumnal sun.
Some of the stuff belonged to my past, the one I experienced a couple of years ago. More belonged to a more distant past, the one I could not remember, or, at the very least, I ought not to remember. And the rest were from another universe, from where my grandma might buy it once, or might have bought it already if the time had taken a different path.
In any case, it wasn't my grandma's backyard I was used to. Not a universe I was used to. I had to test whether the laws of physics were different from the ones I knew.
Inside, one door didn't have a handle. Pure provocation. Even though I wasn't able to slide through them like a ghost, I managed to open them somehow. And close them again, after I found behind them the usual, normal, bedroom as it always had been.
Heading back out across a glass patio, I noticed the affairs in the backyard returned to their more usual state. Quacking, clucking, and barking and in the middle of the commotion, my grandma. She hadn't noticed me though. I tried to get out, but an aggressive duck flew into me, a mother and a stepmother of a large flock of ducklings peacefully grazing all around the house. I was forced to retreat. Or was it two ducks? Yeah, definitely two mean ducks.
Since the front door was not a viable option, I had to find a different way out. Sideway. I just stepped aside to think on it, not realizing there was supposed to be a wall of glass and bricks, barely aware of that fact. I was out.
Grandma's patio ends with a small staircase, so I ended quite a bit up above the ground. It was a time to experiment with flying...
Leaving the backyard behind, I went on to explore the tree tops behind a meadow. My eyes got caught by a beautiful arrangement of a young tree with colorful leaves, dry grass and huge green burdock leaves. I looked at it from all the sides and regretted that I forgot my camera. I told myself I would have to return later.
After buzzing around the meadow, I returned to my beautiful arrangement. What a surprise, it was no longer there. It was just a normal piece of a meadow just like the rest. Time to move on, towards the street.
Flying above the street, I haven't noticed I was losing altitude and that the houses along started to lose their shape, being replaced by something else entirely. I was startled to realize I was suddenly walking on a paved path. The greyish blue setts were layed out in a pattern that caught my attention, mesmerizing me to forget the surprise. As the road collected tributaries and sank into the ground, the walls were tiled in the same pattern.
Taking in the majestic architecture of an anonymous city that I was leaving behind, I walked the length of the subterranean corridor and ended up at a crossroads. Stairway on the right, stairway on the left. After a short hesitation, I decided to go left. I knew where the stairs would lead. To the metro.
The metro station was even more interesting than the maze of corridors. Entering, I could see the whole length of it. Orange brown tiles, but in the same mesmerizing pattern as before. To my right and behind, the rail tracks led into a dark tunnel. My end of the station was flooded with artificial light, the front of the station was bathing in daylight. However, the two sources of light somehow managed to harmonize into a tasteful play of glows and shadows.
Contrary to the empty corridors, the station was full of people. Well, half full. A usual mix of anonymous folk, though slightly more cartoonish, less real than the other details. The details were all around, wherever my eyes rested. Lamps were full of history, nooks and crannies popped out from the background, smudges on the floor revealed stories. The billboards were detailed all over too, except where the ads would have been. Perhaps I just didn't want to see any ads.
The rail tracks were almost at the same level as the platform, just a step lower. And in between the tracks for both directions, there was a third pair of rails. A very unusual one, with a variable gauge. I could see with my own eyes how an entering train switched the the middle track. The wheels came closer together and further apart smoothly, without forcing the train to change speed. A slow speed, but nevertheless.
The purpose of the variable railway gauge remained unknown to me, the train returned to its original track and left into the tunnel. Whether it stopped or not to let people exit or enter, I couldn't remember. Maybe they did so while it was moving. In any case, people were crossing the tracks, to get to the other platform, all around the train. Not like any metro I knew, more like a tram, but not quite. I crossed to the other side too and not knowing what to do, I waited for my train.
I had been interrupted from my waiting by a young man who threw a ball in my direction. An unusual ball that had an inner glow. Not monochromatic and not multiple colors at once.
He'd always thrown it towards me, it would touch the ground, bounce in the original direction and then, unexpectedly, return to its owner. Like a boomerang that could bounce from surfaces. The ball radiated an impression of confidence, as if bouncing into impossible directions was a skill it learned when it was young and now it achieved an aura of elegance about it.
What the heck, I asked myself. I didn't feel like playing catch, especially not with such a strange ball. Nevertheless, I couldn't avert my eyes from it. Thinking about it, thinking about the direction it moved, thinking about the direction I would like it to move, it started to listen to my thoughts as well.
Thus I started to play a game of catch. Sometimes throwing the ball with mostly my hands, other times reaching for it purely with my thoughts. Once, I managed to lose it to the tunnel, which was downhill by the way. Maybe that would have been the end and I could have happily returned to my train waiting.
The tall young man had other plans however, he saved the ball with a bout of willpower. The friend who joined him now might have had to help him or maybe not, they were now two to one. Luckily, a fellow traveller joined my side, turning the game into doubles.
As I started to enjoyed myself, the world started to blur on the edges, getting translucent and dark. I woke up for one last time to tell you my story. The story that would begin with a train arrival.
The train that would take me from this darkness to a world of daylight.

--- layout: post title: Microsoft Office Web Add-ons categories: [] tags: office-integration status: publish type: post published: true meta: {} ---
Recently I posted re some research we have done into Google Docs and Gmail integration. This post shows the result of similar research into building add-ons for Microsoft Office Online.
Online versions of Office applications are different to the native versions in some not so subtle ways, for example in Office Online your document is saved very frequently, also collaborative editing is encouraged, this impacts the design of a Content Manager add-on.
Currently we have a our SharePoint integration and the Web Client Office Online integration, so any potential Office Web add-on needs to be designed to solve a meaningful business problem. It is even conceivable that Email Link might provide a sufficient server side solution.
If you have an interest in Office add-ons get in touch via the usual channels.

Antiplasticarian - noun
1. A person who refrains from eating foods which are wrapped or bagged in plastic.
I realized that if I make up words for not using plastic, like antiplasticarian or sustainatarian, people think it's a "real thing" and accept it.
I've also realized there are immense health benefits that result as a side effect of simply not buying food that comes wrapped in plastic, in the same way vegans benefit from strictly denying any products that come from animals in any way.
Sticking with the No Plastic Diet, aka being antiplasticarian, gives you many health benefits, including:
- avoid meats, except fresh from the docks fish, or straight from the local butcher.
- avoid most manufactured foods
- avoid most foods intended for long shelf life
- and about everything else in the modern supermarket.
It's easier to list what IS available. It's easy to see the positive health effects that not buying plastic could have:
Now you can be the coolest person at the bar and drink from a flask.
The Year Without Plastic encompasses more than just food, but eating is the most difficult habit to change, since we have the impulse to consume multiple times of day, and usually stop at nothing to get a quick bite.
If you are giving this diet a try, let me know how it goes!


Enhanced differentiation of HL-60 leukemia cells to macrophages induced by ciprofibrate.
Abstract
Ciprofibrate, an hypolipidaemic peroxisome proliferator, induced differentiation of HL-60 cells. The effect was greatly potentiated by phorbol 12-myristate 13-acetate at a concentration where neither phorbol ester nor ciprofibrate alone had any effect on these cells. As occurs for HL-60 cell differentiation induced by high phorbol ester concentration, the ciprofibrate-induced phorbol ester-dependent differentiation of HL-60 cells proceeded through the monocytic/macrophage pathway and induced the phosphorylation of proteins with similar molecular weights suggesting that increased protein kinase C activity may be involved in the effect. The peroxisome proliferator-activated receptor (PPARalpha) transcription factor is expressed in HL-60 cells, but no changes were observed in its expression upon HL-60 cell differentiation.

React Component Development
Setup npm for React dev
Add React, React DOM and some form of react scripts as dependencies in package.json. In this example, humanmade/react-wp-scripts is used.
{
"dependencies": {
"react": "^16.4.0",
"react-dom": "^16.4.0",
"react-wp-scripts": "0.2.0"
}
}
Then add a start command to scripts and use react scripts for tests and test:once in package.json
{
"scripts" : {
"start": "react-wp-scripts start",
"test": "react-scripts test --env=jsdom",
"test:once": "CI=true react-scripts test --env=jsdom",
}
}
Notes:
- Test once command once here: https://github.com/facebook/create-react-app/issues/1137#issuecomment-265292520
- If you get an error
SyntaxError: Unexpected token <
from the logo.svg, you probably forgot to change the tests command.
In README.md, document this new script:
### Develop
* `yarn start`
- Runs linter and compiles for development
- Starts test app server
Add Main App Component
Copy this from calderawp/react-start or build your own.
Adding State Management
State Management Development Guidelines
- We use Redux-like state management.
- Try and use 1-2 container components and pass state down to stateless, controlled components.
- A component for UI, should not own its state management. That's a separate concern, it goes elsewhere.
- Use @caldera-labs/state package. If that module does not have the features needed, either add them or make a new module extending it.
- Try to use @wordpress/data over Redux when possible.
Helpful Resources About State Management In React This Way

- https://www.youtube.com/watch?v=v6iR3Zk4oDY
Creating Components
Components must have one responsibility. They can contain components with additional responsibilities.
React Component Guidelines
- controlled components
- Functional, not class components. Redux owns state, we do not need to manage its update cycle. Functional components are highly testable and more likely to play nicely with async rendering
React Component Example
import React from 'react';
import PropTypes from 'prop-types';
/**
* Basic input component
*
* @param {Object} props
* @returns {*}
* @constructor
*/
export const Input = (props) => {
function changeHandler(event){
return props.onValueChange(event.target.value);
}
return (
<input
type={props.inputType}
id={props.id}
className={props.fieldClassName}
aria-describedby={props.ariaDescribedbyAttr}
required={props.isRequired}
onChange={changeHandler}
value={props.value}
/>
);
};
/**
* Prop definitions for Input components
*/
Input.propTypes = {
id: PropTypes.string.isRequired,
fieldClassName: PropTypes.string.isRequired,
help: PropTypes.string,
value: PropTypes.any(
PropTypes.string,
PropTypes.number,
PropTypes.array
),
onValueChange: PropTypes.func.isRequired,
inputType: PropTypes.string.isRequired,
options: PropTypes.array,
ariaDescribedbyAttr: PropTypes.string,
};
/**
* Default props for Input Component
*
* @type {{ariaDescribedbyAttr: string, isRequired: boolean, inputType: string}}
*/
Input.defaultProps = {
ariaDescribedbyAttr: '',
isRequired: false,
inputType: 'text'
};

Creating Exports
This boilerplate compiles code with babel to the/dist
directory. One or more module exports must be created and identified in package.json.
For example:
{
"main": "./dist/index.js",
"files" : [
"./dist/index.js",
"./dist/fields/index.js",
"./dist/fields/factories/index.js"
]
}
See:
Publishing To NPM
All Caldera libraries should be published as org scoped packages in the @caldera-labs organization.
Short version of the docs
Make sure in package.json:
- That
private
is not set to true. - That the name of the package is
@caldera-labs/whatever
wherewhatever
describes the modules job. For example,@caldera-labs/mailchimp-client
if you're building a Mailchimp client. Note that "caldera" was not used on the right side of the slash. - That you have specified at least one entry point and defined a module export for it.
- You have authorization to publish in
@caldera-labs
org scope. - You are logged in as that user via the npm cli
Once you're ready to publish, commit everything and do the first release manually:
npm publish --access public
After that, the documented scripts for automated update publishing apply for future updates.

Harry Potter and the Sorcerer's Stone
Mr and Mrs Dursley, of number four, Privet Drive, were proud to say that they were perfectly normal, thank you very much. They were the last people you’d expect to be nvolved in anything strange or mysterious, because they just didn’t hold with such nonsense.
Mr Dursley was the director of a firm called Grunnings, which made drills. He was a big, beefy man with hardly any neck, although he did have a very large moustache. Mrs Dursley was thin and blonde and had nearly twice the usual amount of neck, which came in very useful as she spent so much of her time craning over garden fences, spying on the neighbours. The Dursleys had a small son called Dudley and in their opinion there was no finer boy anywhere.
The Dursleys had everything they wanted, but they also had a secret, and their greatest fear was that somebody would discover it. They didn’t think they could bear it if anyone found out about the Potters. Mrs Potter was Mrs Dursley’s sister, but they hadn’t met for several years; in fact, Mrs Dursley pretended she didn’t have a sister, because her sister and her good-for-nothing husband were as unDursleyish as it was possible to be. The Dursleys shuddered to think what the neighbours would say if the Potters arrived in the street. The Dursleys knew that the Potters had a small son, too, but they had never even seen him. This boy was another good reason for keeping the Potters away; they didn’t want Dudley mixing with a child like that.
When Mr and Mrs Dursley woke up on the dull, grey Tuesday our story starts, there was nothing about the cloudy sky outside to suggest that strange and mysterious things would soon be happening all over the country. Mr Dursley hummed as he picked out his most boring tie for work and Mrs Dursley gossiped away happily as she wrestled a screaming Dudley into his high chair.
None of them noticed a large tawny owl flutter past the window.

How may I help you?
The pink tax refers to the extra amount women pay daily as consumers. Although these products are often the same but with different packaging, the price discrepancies show a pattern of gender-based pricing.
Through using our website’s “Check” feature, we can see if your product is marked above, below, or approximately the same as other uni-sex marketed products!
By verifying your product doesn’t have gender-based pricing or purchasing products from local, women-owned businesses, you can avoid the pink tax and reclaim the pink!
By clicking the “Feature Me!” button on the home page, you can feature your local, women-owned business and provide an alternative to “pink-tax affected” products!
We are planning to implement an app for Reclaim the Pink with a product scanner, expand our locations, and feature more “pink-tax affected” products.

Paint Devices and Backends
Creating a Paint Device
The QPaintDevice class is the base class of objects that can be painted, i.e. QPainter can draw on any QPaintDevice subclass. QPaintDevice's drawing capabilities are among others implemented by QWidget, QImage, QPixmap, QPicture, QPrinter, and QOpenGLPaintDevice.
| Widget The QWidget class is the base class of user interface elements in the Qt Widgets module. It receives mouse, keyboard and other events from the window system, and paints a representation of itself on the screen. |
| Image The QImage class provides a hardware-independent image representation which is designed and optimized for I/O, and for direct pixel access and manipulation. QImage supports several image formats including monochrome, 8-bit, 32-bit and alpha-blended images. One advantage of using QImage as a paint device is that it is possible to guarantee the pixel exactness of any drawing operation in a platform-independent way. Another benefit is that the painting can be performed in another thread than the current GUI thread. |
| Pixmap The QPixmap class is an off-screen image representation which is designed and optimized for showing images on screen. Unlike QImage, the pixel data in a pixmap is internal and is managed by the underlying window system, i.e. pixels can only be accessed through QPainter functions or by converting the QPixmap to a QImage. To optimize drawing with QPixmap, Qt provides the QPixmapCache class which can be used to store temporary pixmaps that are expensive to generate without using more storage space than the cache limit. Qt also provides the QBitmap convenience class, inheriting QPixmap. QBitmap guarantees monochrome (1-bit depth) pixmaps, and is mainly used for creating custom QCursor and QBrush objects, constructing QRegion objects. |
| OpenGL Paint Device As mentioned previously, Qt is offering classes that makes it easy to use OpenGL in Qt applications. For example, the QOpenGLPaintDevice enables the OpenGL API for rendering with QPainter. |
| Picture The QPicture class is a paint device that records and replays QPainter commands. A picture serializes painter commands to an IO device in a platform-independent format. QPicture is also resolution independent, i.e. a QPicture can be displayed on different devices (for example svg, pdf, ps, printer and screen) looking the same. Qt provides the QPicture::load() and QPicture::save() functions as well as streaming operators for loading and saving pictures. |
| Custom Backends Support for a new backend can be implemented by deriving from the QPaintDevice class and reimplementing the virtual QPaintDevice::paintEngine() function to tell QPainter which paint engine should be used to draw on this particular device. To actually be able to draw on the device, this paint engine must be a custom paint engine created by deriving from the QPaintEngine class. |

Flickr was too new to use back in the heady days of early 2005, so I decided to take matters into my own hands and collect photos in these hand-spun picture posts. And in case you were wondering, photos + blog = phlog.

[gecode-users] Element restriction is correctly used in MPG?

Hello group.
I have been studying the TSP example that is in the gecode.org site package
and I have the following doubt regarding the element function:
IntVar p0 (* this, 0, n - 1);
element (* this, succ, p0, 0); // here (1)
rel (* this, p0, IRT_LE, succ [0]);
According to 'MPG.pdf' pg. 70 (4.4.12):
element (home, c, x, y) // (2)
Says, variable y to be the element of the array c at index x, then how can
it be possible (1) ???
regards
Alex

I need to figure out how where to rehost my newsletter content. There was a lot of good stuff in there, even if it had the same challenge of any regularly-published content and thus a mix of stuff that is just fine as well.


Exact package name to watch, or space delimited list of packages to match
Note, that multi-package works only for old api, and may not work as expected.
the builds of all space split packages are obtained and fitlered, and the logic is applied to the merged list.
So for eg "A B" if package A have 10 very old builds, and package B ten very new builds, only builds of B will be processed.
If you suddenly build A, then it willbe of course pulled.

The type on this site is totally unorthodox and it’s easier to read. If you don’t believe me, here’s why…
I’m sick and tired of cramped websites that have tiny type and don’t use the whole screen well. I’ve come to believe that the problem with reading on a screen isn’t the backlight—it’s that the type is too freaking small. Most designers don’t even know that there is an optimal number of characters per line. Let me take you through some of my thinking so that you can consider if you can take away any ideas to use on a project of your own. The fact you’ve read to this paragraph is proof that there is something to my argument.
#1 — I want my site to read like a book
Screen reading should mimic printed reading. Why does web type resemble dictionary reading? Information Architects on designing for easy reading. I often hear people complain that they don’t like reading on a screen because of the backlight—I believe the real reason is tiny type. Reading online is more analogous to reading a dictionary than reading a book. The text is small and thin columned, it’s obvious that the designers goal was to fit a lot of information into a small amount of space. This may work for some applications, but lengthy reading is definitely not one of them.
#2 — To achieve optimal characters per line
On each full paragraph line of text on this blog there are about 75 characters—which is widely regarded as the most characters that you can put on a line and still have it optimal for readers.
“Anything from 45 to 75 characters is widely regarded as a satisfactory length of line for a single-column page set in a serifed text face in a text size. The 66-character line(counting both letters and spaces) is widely regarded as ideal. For multiple column work, a better average is 40 to 50 characters.” The Elements of Typographic Style Applied to the Web
#3 — Text should be not too long and not too short
Optimal characters per line are a big deal—if the message you’re writing is important you want to remove any barrier to your readers connecting with your message. Here is a quote about why line length matters from the Baymard Institute:
Too long – if a line of text is too long the visitor’s eye will have a hard time focusing on the text. This is because the length makes it difficult to get an idea of where the line starts and ends. Furthermore it can be difficult to continue from the correct line in large blocks of text.
Too short – if a line is too short the eye will have to travel back too often, breaking the reader’s rhythm. Too short lines also tend to stress people, making them begin on the next line before finishing the current one (hence skipping potentially important words).
#4 — I want readers to engage—so I lost the noise
For years I’ve taught dozens of authors how to write online by pointing them to the best article I’ve ever read on how we read online. In this article they refer to Jakob Nielson‘s philosophy of the motivation of the reader:
Nielsen champions the idea of information foraging. Humans are informavores. On the Internet, we hunt for facts. In earlier days, when switching between sites was time-consuming, we tended to stay in one place and dig. Now we assess a site quickly, looking for an “information scent.” We move on if there doesn’t seem to be any food around.
I designed this site to give an “information scent” with a large title, quick summary, and hook. Then I focus on removing distraction and delivering the best writing I can.
UPDATE: #5 — Line height matters
To ensure that your type can be readable it’s important to let the lines of type breathe. There is actually a ratio between type size, characters per line, column width, and line height. You can use this great calculator to help dial it in.
Conclusion
I hope that this article has at least caused you to think about the way your web page displays text.I would love to hear your thoughts on this. Time will only tell if this set up will be fruitful.

--- layout: post title: ! 'Rails 3.2 RC1: Faster dev mode & routing, explain queries, tagged logger, store' categories: - releases author: David published: true date: 2011-12-20 00:46:00.000000000 +00:00 ---
Once you’ve boarded the Rails train, you just know that every stop along the way is going to be a good time. This release candidate is no different and we’ve packed it with loving goodies without making upgrading a hassle.
Faster dev mode & routing
The most noticeable new feature is that development mode got a ton and a half faster. Inspired by Active Reload, we now only reload classes from files you’ve actually changed. The difference is dramatic on a larger application.
Route recognition also got a bunch faster thanks to the new Journey engine and we made linking much faster as well (especially apparent when you’re having 100+ links on a single page).
Explain queries
We’ve added a quick and easy way to explain quieries generated by ARel. In the console, you can run something like puts Person.active.limit(5).explain
and you’ll get the query ARel produces explained (so you can easily see whether its using the right indexes). There’s even a default threshold in development mode where if a query takes more than half a second to run, it’s automatically explained inline — how about that!
Tagged logger
When you’re running a multi-user, multi-account application, it’s a great help to be able to filter the log by who did what. Enter the TaggedLogging wrapper. It works like this:
Logger = ActiveSupport::TaggedLogging.new(Logger.new(STDOUT)) Logger.tagged(“BCX”) { Logger.info “Stuff” } # Logs “[BCX] Stuff” Logger.tagged(“BCX”) do Logger.tagged(“Jason”) do Logger.info “Stuff” # Logs “\[BCX\] \[Jason\] Stuff” end endActive Record Store
Key/value stores are great, but it’s not always you want to go the whole honking way just for a little variable-key action. Enter the Active Record Store:
class User < ActiveRecord::Base store :settings, accessors: [ :color, :homepage ] end u = User.new(color: ‘black’, homepage: ‘37signals.com’) u.color # Accessor stored attribute u.settings[:country] = ‘Denmark’ # Any attribute, even if not specified with an accessorThese are just a few of the highlights. The full release notes detail every loving change.
Given that this is a release candidate, we’re ever so eager to hear your feedback. We hope it’ll be a quick RC phase, but please do spoil that plan by reporting bugs.
As always, you install a release candidate by doing gem install rails --pre

RUSH HOUR RATING: 7 / 10 --> Good movie
For more reviews and trivia, go to http://surf.to/joblo
Another action/comedy-buddy flick pits Hong Hong sensation Jackie Chan aside Hollywood's latest Eddie Murphy wannabee Chris Tucker. Director Brett Ratner, who directed Tucker in his "break-out" comedy, MONEY TALKS (6/10), helms this melange of the original 48 HOURS (7.5/10) and the original BEVERLY HILLS COP (8/10).
PLOT: A Hong Kong businessman's daughter is kidnapped for ransom. The FBI attempts to solve the case, while the Hong Kong man brings in his own private agent to help (Chan). The FBI wants to keep the new guy out of their hair, and delegate this task to one of their lowliest LAPD cops (enter Tucker). Stuck with each other, the unorthodox duo attempt to solve the case for themselves. Fun and action ensues.
CRITIQUE: Funny movie chopped full of action, lacks an original concept and plot line, but comes through with hilarious banter from Tucker and fun fight scenes with Chan. I found this film's main point of interest to be Chris Tucker's verbal potpourri of mild profanity and humour, but appreciate the fact that folks who don't enjoy the man's abilities may be turned off from this film. He reminded me a whole bunch of the young Eddie Murphy before the fame went to his head...vibrant, original and voracious for laughs!
Chan is also a great combo for Tucker's motormouth, with his lack of English pronunciation, swift moves and graceful stuntwork. Chan is considered the straight man in this film, and works on that level. Some of his fans may be put off by the fact that he doesn't joke around as much as his other flicks, but all in all, the duo clicked for me, and that's what led this film to the recommendation arena. Some low points include the ho-hum story line, the obvious use of "hip" songs to pad some retarded scenes, and the lowly, and I do mean lowly, appearance by Chris Penn as a fat-ass con-man (es tu Penn?). How this man's career went from RESERVOIR DOGS (9/10) to playing fourth banana in Chan movie, I'll never know!
Overall, I will suggest this film to all those who appreciate the work of Chris Tucker (I liked him in most of his films, except FIFTH ELEMENT (6.5/10), in which I thought his wild animation was terribly out of place) and Jackie Chan. At the same time, I must say that if you are not a big fan of either star, and/or if you are looking for an interesting story line, skip this sucker and go back and rent either one of the Murphy movies that I mentioned earlier. One more thing, as per usual at the end of every Chan movie, this film includes goofs during the credits, which are just as (if not funnier) than most of the humour in this film. Stay tuned!
Little Known Facts about this film and its stars: As of September 1998, this film held the greatest box-office opening weekend of any other September release ever ($31 million.) Director Brett Ratner is engaged to actress Rebecca Gayheart. Jackie Chan's real name is Kong Sung Chan, which means "born in Hong Kong".  He stands 5"7. Chris Tucker was born in Atlanta, Georgia, with three older brothers and two older sisters. He was voted as the "Most Humorous member" of his high school graduating class.
Review Date: September 26, 1998 Director: Brett Ratner Writers: Jim Kouf, Ross LaManna and Jeff Nathanson (uncredited) Producers: Arthur M. Sarkissian, Roger Birnbaum and Jonathan Glickman Actors: Chris Tucker as Detective James Carter Jackie Chan as Detective Inspector Lee Genre: Comedy/Action Year of Release: 1998

Detailed Description
The QCameraFocusZone class provides information on zones used for autofocusing a camera.
For cameras that support autofocusing, in order for a camera to autofocus on part of a sensor frame, it considers different zones within the frame. Which zones to use, and where the zones are located vary between different cameras.
This class exposes what zones are used by a particular camera, and a list of the zones can be retrieved by a QCameraFocus instance.
You can use this information to present visual feedback - for example, drawing rectangles around areas of the camera frame that are in focus, or changing the color of a zone as it comes into focus.
focus->setFocusPointMode(QCameraFocus::FocusPointAuto); QList<QCameraFocusZone> zones = focus->focusZones(); foreach (QCameraFocusZone zone, zones) { if (zone.status() == QCameraFocusZone::Focused) { // Draw a green box at zone.area() } else if (zone.status() == QCameraFocusZone::Selected) { // This area is selected for autofocusing, but is not in focus // Draw a yellow box at zone.area() } }

I came to Chicago to volunteer with City Year, an education-focused nonprofit that also ensures volunteers are growing as individuals and leaders during their year of full-time service. I became fascinated and passionate about the state of education in our country, especially in Chicago, and decided to stay. I joined staff and became a manager, and while I still feel passionate about education, I realized that I needed to know something more to make an impact. Which brought me here, to Dev Bootcamp, to learn programming and development skills that I hope to use to better our education system, empower our teachers, and teach our students.
I have an array of interests but you can usually find me reading, talking about dinosaurs, oggling over animal skeletons and paraphenilia, eating cheese and watching the Packers, or playing Dungeons and Dragons or boardgames.

Module Information


Boolean Operations
Requirements
COMPAS
compas_libigl
compas_viewers
Install instructions for each of the requirements are available in their respective repos:
Experimental
All requirements can be installed in one go in a custom environment using the environment files included here:
conda env create -f environment_osx.yml
Input Geometry
In this example, we will create two boxes and apply various boolean operations to them: union, intersection, and difference.
We use compas.geometry
to create the box shapes, and compas.datastructures
to convert them to triangle meshes.
from compas.geometry import Box
from compas.datastructures import Mesh
A box can be created around the origin with a chosen width, height, and depth.
We will create box a
with width=5.0
, height=3.0
, and depth=1.0
,
and box b
with width=1.0
, height=5.0
, and depth=3.0
.
a = Box.from_width_height_depth(5.0, 3.0, 1.0)
b = Box.from_width_height_depth(1.0, 5.0, 3.0)
A Box
is a Shape
and any Shape
can be converted to a mesh.
a = Mesh.from_shape(a)
b = Mesh.from_shape(b)
The boolean operations only work on triangle meshes. The meshes resulting from shapes are quads. Therefore we have to convert the quads to triangles.
a.quads_to_triangles()
b.quads_to_triangles()
Operations
For the boolean operations we use compas_libigl
.
import compas_libigl as igl
The wrapper functions use generic representations of meshes with lists of vertices and faces as input and output.
A = a.to_vertices_and_faces()
B = b.to_vertices_and_faces()
C = igl.mesh_union(A, B)
c_union = Mesh.from_vertices_and_faces(*C)
C = igl.mesh_intersection(A, B)
c_intersection = Mesh.from_vertices_and_faces(*C)
C = igl.mesh_difference(A, B)
c_diff = Mesh.from_vertices_and_faces(*C)
Viewer
The result can be visualized using the MultiMeshViewer
of compas_viewers
.
The viewers are not part of core COMPAS and have to be installed separately.
Installation instructions are available here.
from compas_viewers.multimeshviewer import MultiMeshViewer
Note
If you can’t or don’t want to install the viewers, you can skip to Blender or Rhino for visualization using CAD software.
This is the final script using the MutliMeshViewer
for visualisation.

viewer.show()
Blender
To run this example in Blender, make sure that COMPAS and compas_libigl
are installed for Blender.
For detailed instructions, see Install COMPAS for Blender.
For visualisation we import Blender artists instead of the MultiMeshViewer
.
from compas_blender.artists import MeshArtist
Everything else is the same. The complete script for Blender is available here:
Rhino
To run this example in Rhino, make sure that COMPAS is installed for Rhino. For detailed instructions, see Install COMPAS for Rhino.
In Rhino, the functionality from compas_libigl
cannot be called directly because the wrappers
for the C++ code of libigl
are generated using PyBind11.
Instead we use Remote Procedure Calls.
The required changes to the original code are minimal, but the RPC server needs to be set up properly. See the tutorial for more information: Remote Procedure Calls.
Instead of importing compas_libigl
directly as before, we create a Proxy
for the library.
from compas.rpc import Proxy
igl = Proxy('compas_libigl')
For visualisation we import Rhino artists instead of the MultiMeshViewer
.
from compas_rhino.artists import MeshArtist

java.lang.Object org.omg.CORBA.LocalObject
public class LocalObject
Used as a base class for implementation of a local IDL interface in the Java language mapping. It is a class which implements all the operations in the org.omg.CORBA.Object interface.
Local interfaces are implemented by using CORBA::LocalObject
to provide implementations of Object
pseudo
operations and any other ORB-specific support mechanisms that are
appropriate for such objects. Object implementation techniques are
inherently language-mapping specific. Therefore, the
LocalObject
type is not defined in IDL, but is specified
in each language mapping.
Methods that do not apply to local objects throw
an org.omg.CORBA.NO_IMPLEMENT
exception with the message,
"This is a locally contrained object." Attempting to use a
LocalObject to create a DII request results in NO_IMPLEMENT
system exception. Attempting to marshal or stringify a
LocalObject results in a MARSHAL system exception. Narrowing
and widening references to LocalObjects must work as for regular
object references.
LocalObject
is to be used as the base class of locally
constrained objects, such as those in the PortableServer module.
The specification here is based on the CORBA Components

public boolean _is_equivalent(Object that)
Determines whether the two object references are equivalent, so far as the ORB can easily determine. Two object references are equivalent if they are identical. Two distinct object references which in fact refer to the same object are also equivalent. However, ORBs are not required to attempt determination of whether two distinct object references refer to the same object, since such determination could be impractically expensive.

public class AVLGTree<T extends java.lang.Comparable<T>> extends java.lang.Object
AVLGTree
is a class representing an AVL Tree with a relaxed balance condition. Its constructor receives a strictly positive parameter which controls the maximum imbalance allowed on any subtree of the tree which it creates. So, for example:- An AVL-1 tree is a classic AVL tree, which only allows for perfectly balanced binary subtrees (imbalance of 0 everywhere), or subtrees with a maximum imbalance of 1 (somewhere).
- An AVL-2 tree relaxes the criteria of AVL-1 trees, by also allowing for subtrees that have an imbalance of 2.
- AVL-3 trees allow an imbalance of 3.
- ...
The idea behind AVL-G trees is that rotations cost time, so maybe we would be willing to accept bad search performance now and then if it would mean less rotations. On the other hand, increasing the balance parameter also means that we will be making insertions faster.

Constructor Detail
-
AVLGTree
public AVLGTree(int maxImbalance) throws InvalidBalanceException
The class constructor provides the tree with the maximum imbalance allowed.- Parameters:
maxImbalance
- The maximum imbalance allowed by the AVL-G Tree.- Throws:
InvalidBalanceException
- if maxImbalance is a value smaller than 1.
-
-
Method Detail
-
insert
public void insert(T key)
Insert key in the tree. You will not be tested on duplicates! This means that in a deletion test, any key that has been inserted and subsequently deleted should not be found in the tree! s- Parameters:
key
- The key to insert in the tree.
-
delete
public T delete(T key) throws EmptyTreeException
Delete the key from the data structure and return it to the caller.- Parameters:
key
- The key to delete from the structure.- Returns:
- The key that was removed, or
null
if the key was not found. - Throws:
EmptyTreeException
- if the tree is empty.
-
search
public T search(T key) throws EmptyTreeException
Search for key in the tree. Return a reference to it if it's in there, or
null
otherwise.- Parameters:
key
- The key to search for.- Returns:
- key if key is in the tree, or
null
otherwise. - Throws:
EmptyTreeException
- if the tree is empty.
-
getMaxImbalance
public int getMaxImbalance()
Retrieves the maximum imbalance parameter.- Returns:
- The maximum imbalance parameter provided as a constructor parameter.
-
getHeight
public int getHeight()
Return the height of the tree. The height of the tree is defined as the length of the longest path between the root and the leaf level. By definition of path length, a stub tree has a height of 0, and we define an empty tree to have a height of -1.
- Returns:
- The height of the tree. If the tree is empty, returns -1.
-
isEmpty
public boolean isEmpty()
Query the tree for emptiness. A tree is empty iff it has zero keys stored.- Returns:
true
if the tree is empty,false
otherwise.
-
getRoot
public T getRoot() throws EmptyTreeException
Return the key at the tree's root node.- Returns:
- The key at the tree's root node.
- Throws:
EmptyTreeException
- if the tree is empty.
-
isBST
public boolean isBST()
Establishes whether the AVL-G tree globally satisfies the BST condition. This method is terrifically useful for testing!
- Returns:
true
if the tree satisfies the Binary Search Tree property,false
otherwise.
-
isAVLGBalanced
public boolean isAVLGBalanced()
Establishes whether the AVL-G tree globally satisfies the AVL-G condition. This method is terrifically useful for testing!
- Returns:
true
if the tree satisfies the balance requirements of an AVLG tree,false
otherwise.
-
clear
public void clear()
Empties the AVL-G Tree of all its elements. After a call to this method, the tree should have 0 elements.
-
getCount
public int getCount()
Return the number of elements in the tree.
- Returns:
- The number of elements in the tree.
